WILLIAM J. CLARK, or CHICAGO, ILLINOIS? DRIP DEVICE FOR STEAM SYSTEMS.

Specification of Letters Patent.

Application filed May 31, 1904. Serial No.- 210,385.

Patented Jain-30, 1906.

.To all whom it neay concern:

-Be it known that 1, WILLIAM J. CLARK, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Drip Devices for Steam Systems, of which the following is a description.

My device belongs to that class of devices particularly intended to convey the fluid accumulating by reason of condensation in steam systemssuch, for example, as heating systems to some suitable point and then discharging the same through a drip device, which preferably may be regulated as desired by suitable valve devices.

The object is to produce a simple and effective device for the purpose which shall be kept sufliciently warm by the passing steam to prevent the freezing of the drip and the consequent interference with the functions of the device.

To this end my invention consists in the novel construction, arrangement, and commy invei'ition.

bination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like referencenumbers indicate like or corresponding parts, Figure 1 1s a longitudinal section through a section of a steam-pipe, showing Fig. 2 is a transverse section through the pipe and drip device, showing a modification in which both the controlling valve and the drip-nozzle are located within the steam-pipe. Fig. 3 is a side view of the valve shown in Fig. 2 with parts partially broken away to show the construction. Fig. 4 is a transverse section showing a slightlymodified form; and Fig. 5 is a view similar to Fig. 1, with the exce tion that the valve is not shown. Such a orm is adapted for use on railway-cars, in which the valve is located inside the car.

In the drawings, 1 represents a section of pipe constructed to be connected with and form a part of a steam system, the connecting-pipes in the drawings being indicated by 2 2.

3 is a drip-nozzle carried by the section 1 in such a manner as to be warmed by the passing steam therein. The nozzle 3 is preferably extended through and formed integral with the section 1, as clearly shown in the drawings.

In the form'shown in Fig. 1, 4. indicates the drippipe conducting the products of condensation to the valve 5, controlled by the stem 6, whereby the fluid may be conducted through the nozzle 3, which is constantly warmed by the steam passing thereabout. It will be readily seen that by this means the nozzle is kept warm by means of the passing steam without the loss or escape of any steam, the action being substantially automatic and requiring no attention.

In Fig. 2 the nozzle 3 is located substantially as shown in Fig. 1, with the exception that the valve 5 is also carried within the pipe, in which case the danger of the fluid in any portion of the device freezing is obviated.

Fig. 4 is a slight modification of the form shown in Fig. 2, in which the drip-pipe extends horizontally through the pipe, and the parts are correspondingly constructed for that position. The operation is the same.

My device is particularly adapted for use in positions which are exposed to low tempe atures-such, for example, as in use upon cars and in all places where the drip is likely to be frozen.

It is obvious that after having described my improvement various immaterial modifications may be made without departing from the spirit of my invention. Hence I do not wish to be understood as limiting my self to the exact form and construction shown.

Having thus described my invention, what I claim as new and desire to secure b Letters Patent, is-

1. A pipe-fitting of integral structure, com- .prising a section of pipe forming a chamber provided with means for connecting the same in a pipe-line, and a drip-pipe extending transversely throughthe chamber, the outlet end of the drip-pipe terminating at a point substantially in line with the wall of the chamber. w

2. A pipe-fitting comprising a section of pipe with means for connecting the same in a pipe-line, provided with a drip-nozzle formed integral with the fitting and extending transversely through the chamber, the outlet end of the drip-pipe terminating at a point substantially in line with the wall of the chamber, and a valve controlling the dripnozzle.

3. A pipe-fitting comprising a section of pipe constructed with means or connecting the same in a pipeline provided with a dripnozzle formed integral With the fitting and extending transversely therethrough, in comthrough, the outlet end of the drip-nozzle terminating at a point substantially in line with the wall of the chamber, in combination with a valve for the drip-nozzle arranged at a point therein within the chamber, and means outside the chamber for controlling the valve.

5. In a heating system, the combination with a conduit for the heating medium, of a drip-nozzle projecting transversely through the conduit and exposed on all sides to the direct action of the heating medium as the same passes through the conduit, the outlet end of the drip-nozzle terminating at a point substantially in line with the Wall of the chamber.

6. A steam system comprising a steampipe, and a drip-pipe connected thereto, the outer wall of the drip-pipe being in the direct path of the passing steam in said first-mentioned pipe and surrounded by the latter, the outlet end of the drip-pipe terminating substantially at the wall of the steam-pipe.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses. A
